GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 271,074, dated January23, 1883.

Application filed July 24, 1882. (No model.)

To all whom it may concern:

Be it known that I, EDWARD W. JENKINS, of Chicago, in the county of(look and State of Illinois, have invented certain new and usefulImprovements in Grain-Binders, of which the following is aspecification.

My invention relates to that class of automatic binders, whether usingcord or wire, in which the binding mechanism is tripped or to throwninto action through the instrumentality of the accumulating gavel, sothat the sheaves shall be of a practically uniform size.

and density; and it consists in combining with theshipping-lever of thebinder clutch a packer 1 arranged to mount by the impact of its teethupon the accumulating gavel, thereby moving said lever; in combiningwith the grain-receptacle a rotating toothed packer mounted at the heador throat thereof in such manner as to be allowed a bodily-mountingmovemeut,with the impact of its teethupon the accumulating andcompressed gavel, and connect-ions between said packer and theshippinglever which controls the binder-clutch to cause the engage- 2ment or disengagement of said clutch; in combining with the binderclutchand its shipping-lever, and with the grain-receptacle, a rotary toothedpacker carried upon one end of a longitudinally movable support, withits teeth projecting into the throatway of said receptacle, and a leverintermediating between the other end of said support and the free end ofthe shipping-lever, whereby the latter will be operated by the mountingof the packer upon or behind the accumulating gavel; in

combining with a tripping-packer in the throatway of thegrain-receptacle a positively-operated compressor or cut-off closing theexit side of said receptacle until started by the tripping 40 of themachine; in an improved clutch consisting of a toothed or ratchetedclutch-half affixed to one of two abutting shafts, and a spring-pressedtoothed dog or carrier transversely pivoted to the other, and in thevarious other combinations and details of construction hereinafterdescribed and claimed.

In the drawings, Figure 1 is a rear sectional elevation of so much of aharvester and binding attachment embodying my invention as is necessaryto a complete understanding of the latter. Fig. 2 is an outer or stubbleside view, the harvester being omitted; Figs. 3 and 4, side and frontelevations of thepacker enlarged; and Figs. 5, 6, 7, and 8, details ofthe clutch and its shipper enlarged.

A represents the main wheel of the harvester, and B the elevator-frame.A beam, 0, supported by or from the outer elevator-struts, or, ifconvenient, one of the harvester-sills, carries the receiving side ofthe binder-f'ame, a portion of which only is shown, the dlscharge sideof said frame being borne upon the outside sill of the harvester, or inany suitable manner.

Properly mounted in the binder-frame, be- 6 5 neath the decking or.grain-table, is a constant- Iy-rotating shaft, D, hereinafter called thedriving-shaft, driven from the harvester by chain and sprocket wheel orother gearin This driving-shaft, in the present instance, does not passentirely beneath the binder-frame; but as to its inner, and herein theforward, end terminates about midway of the width thereof, and near saidend is provided with a fast clutch-half, d, preferably ratchet-toothedto act in one direction only. It also has near this clutch-half a chainor sprocket wheel, d, by which the packer is driven, as will hereinafterappear. 7

In line with the driving-shaft and abutting against its inner end is thebinder-shaft E, by. which the actual binding devices are driven. Keyedor bolted to the abutting-end of this shaft is a tubular head or block,E, which, for the purpose of keeping the two shafts steadily in line attheir meeting-point, takes over and serves as a bearing for so much ofthe inner end of the driving-shaft as projects beyond the clutchhalf. Tothisblock, or to cars projecting therefrom, is pivoted by a transverse opivot a carrier or dog, 6, having a tooth or ,lug, c, projecting towardthe toothed face of the driving clutch-half, and urged toward the latterby means of a spring, c seated against a lug upon the block. So long asthe carrier. 5 is in engagement with the opposing clutchhalf thebinder'shaft will be locked to and revolve with the driving-shaft, thusactuating the binding mechanism; but whenever it is disconnected orthrown out of engagement the binder-shaft and mechanism driven therebywill come to a stop and remain at rest. Such disengagment is caused atthe end of each complete revolution of the binder-shaft by means of aswitch-lever, F, tulcrnmed atf to a lug or lugs projecting from thetubular casting or su tiporting-bar G, one end of said lever normallyresting just over and between the carrier and clutch-half, and having aninclined face,f, which is struck by and forces aside an anti-frictionroller, or it may be alug, 6 upon the crown of the carrier as the latterapproaches the end of a revolution, thereby swinging said carrier backupon its pivot, away from and out of engagemet with the clutchhalf,and'by the contact between the anti-friction wheel and inclinepreventing re-engagelnent so long as the lever is undisturbed.

Bolted fast to the beam U is a standard. H, forming part of, orcorresponding in outline with, the grain board or ch ute-that is,extending upwardly and bending in to a termination immediately beneaththe discharge-point of the elevator. 1n the present instance the body ofthe standard is formed of two side bars, h, spaced by a block, it, atthe head, and by the bolts which hold it to the beam at the foot, so asto afi'ord ledges to said chute and to the inner side of the slottedbinding-table I. on either side of the path of the binder-arm, as itmoves on its pivot to place the wire or cord around the gavel and -carryit into the bandsecuring devices.

The binding mechanism may be that of the well-known McCormickreciprocating binder, in which case the binder-arm will, enter betweenthe ledges from above; or it may be of some other type, with thebinder-arm working upon a stationary pivot, either above or beneath thechute. Thelength and outline of the binding-table will of course dependon the style of said binding mechanism.

K is a rotary fingered wheel, running upon aspindle, is, upon the upperend of a'support, connected by a link, 70 at said end to the standard H,near the head or throatway ot' the chute. The fin gerst' of said wheelare preferably pivoted thereto, and have their heels formed as shoes,which travel upon a cam or eccentric t" arran ed in such manner that thefingers, as they are brought up toward the incoming grain,'assume andare held in a radial position to strike and force it onward,but when atthe limit of their effective action are permitted to fold back upontheirpivots, to be readily withdrawn from the stream. The fingers may,however, so far as regards other Ieatures of my invention, be rigid withthe wheel, and curved or set back from the direction of rotation, as incertain forms of packers or feeders already well known. The support k,bearing the fingered wheel, packer, or feeder, is pivoted at its lowerend to one arm, l, of

nection allowing relative play. To thislast mentioned arm may also beapplied an adjustable counterbalancc, Z whereby the sensitiveness of thedevice may be determined.

A chain, M, runs from the sprocket-wheel d over guide-pulleys at, one ofwhich may be on the pivot-pin connecting the lever-arm Z and support It,and the other mounted in a spur or projection, 70 from the latter, uptoand over the sprocket-hub of the packer to drive it.

While a gavel is collecting, exit from the grain-receptacle will beclosed by the strand of cord or wire stretched across the passage. way,or by a compressor or stop, which at the proper moment will be withdrawnor swiing away to allow discharge. It is preferable to relieve the bandmaterial, so far as possible, of this duty, and therefore, while anyform of compressor or stop adapted to co-act with the otherinstrumentalities of my invention may be employed, if so desired, Ipropose to mount at a suitable height above the receptacle and near tothe head of the chute a rock-shaft, N, carrying pendent tines N, ofsufficient length to block the passage of the grain when down. Thesetines have at first a straight body, a, which brings them near to thepacker or feedwhcel, and forms, in connection with the chute, at thatpoint a throatway for the action of said wheel; then they curve orbulgeout. at n to gain space for the gavel and properly shape it. Thetines are held closed and swung open at the proper periods by means of apitman, 0, connecting with a crank, 0, upon the rockshaft, and moved byany suitable part of the a mechanism driven by the binder-shaft, atoggle, 0, being interposed between the end of .said pitma-n and thecrank 0, in order to increase the oscillation of the shaft, andconsequent throw of the tines to open them rapidly and widely.

In the operation of the machine, the grain accumulating in thereceptacle and against the tines or other stop gradually backs up in amore orlesscompactmass againsttherotatingwheel, which, as its fingersmeet with increasing resistance, will mount or roll to retain itsposition upon the crest or rear side of said mass, pulling with itthesupport 7c, and therebyrocking the lever L and depressing the freeend of the shipper. This movement of the latter throws its inclined faceout of contact with the carrier, which thereupon springs into engagementwith the toothed clutch-half on the driving-shaft, and the binder isstarted, takes the gavel, the tines open for its discharge or re- IOUnioval, bound or unbound, as the case may be, are immediately reclosed,and the fingered wheel returns to its first position, again setting theshipper to meet and disengage the carrier as the binder-shaft completesits revolution.

When the gavel is to be encircled and completely bound within theabove-described rereptacle the rotary fingered wheel may serve both as atripping device and as a packer to consolidate the mass preparatory tobinding, and the tines or other stop. as an outside compressor, actingin opposition to the bindinga-rm until the ends of the band are unitedand the sheaf is ready to be discharged. If, however, a McCormickreciprocating binder is used,

or with some other types which either do not complete or do not commencethe binding operation in the receptacle, the otfice of the rotaryfingered wheel may be merely to trip the binding mechanism at the propermoment, not notably to pack or compress the gavel for the reception ofthe band, and the tines will be thrown open as soon as the gavel isgrasped for removal.

Should the binder be low level, receiving directly from theharvester-platform without the intervention of an elevator, a spring orequivalent device may be applied to the feedwheel support or to theshipper to reset the tripping mechanism after the discharge of a gavelor sheaf. Such an instrumentality may also be employed where the wheelis to act as a packer to subject the grain to marked compression.

It is obvious that instead of mounting the feed-wheel upon alongitudinally-moving support it may be borne in one arm of a crankedlever; that the form of the clutch may be varied and the shipper and itslever-connections suitably modified to control it; that, according tothe nature of the clutch, the binder-shaft may be out of line with thedriving-shaft, and that various other'changes in matters of detail or ofa subordinate character may be made without departing from the principleof my iiivention.
